Loop which Checks Values of Matrix

M = [2.7 , 1.9 , 0.75 , 0.16 , 0.35]

I have a matrix and I would like it to check each element and replace it with a new number or leave the old one depending on the parameter taken.

if element is bigger than c=1 make new element from formula

and if smaller do nothing with that number

I do not know how difficult or simple it is.

I am just starting my adventure with loops and I am counting on help here

"...make new element from formula"

What is the formula?

[Adam Rak]

a formula that uses an element from the matrix M and W

M = [2.7 , 1.9 , 0.75 , 0.16 , 0.35];

W = [a b c d e];

new_number = 2.7*a

new_number2 = 1.9*b

new_number3 = 0.75 (old number because of 0.75<c)

...

Forget about loops, learn the MATLAB approach using indexing:

c = 1;
W = [4,3,5,2,3];
M = [2.7,1.9,0.75,0.16,0.35]

M = 1×5

2.7000 1.9000 0.7500 0.1600 0.3500

X = M>c;
M(X) = M(X).*W(X)

M = 1×5

10.8000 5.7000 0.7500 0.1600 0.3500

Answer 2

[Voss]

M = [2.7 , 1.9 , 0.75 , 0.16 , 0.35];
c = 1;

for ii = 1:numel(M)
    if M(ii) > c
        M(ii) = % new element from formula
    end
end

(assuming the objective was to learn how for loops work)
